This whole situation with students cheering and booing is kind of strange.
Aren't students, at least anecdotally, outsourcing a lot of _their_ work to LLMs? And upon graduation when they're told that it's their future they don't like it?
For everyone comparing an EU-wide initiative to country-specific ones keep in mind that EU is composed of 28 sovereign states. Many individual countries already have their payment systems, and have had for a long while.
It's not equivalent to India, or the US.
It'd be more comparable to ASEAN (11) or the Arab league (22).
Businesses with slim margins in Germany simply do not have Visa/Mastercard -- only "EC", the German network. Thay means it's not a matter of passing on cost, but it's a choice for the consumer: cash or EC.
If I had to guess, having subbbed to the EC network, or any of the other country specific ones, merchants would simply get the new one as well automatically.
Similar things are happening with online ID where an EU-wide provider is being rolled out and if you as a service provider need KYC-type ID you integrate only with it. Under the hood the user can use any of the national IDs.
It seems to me that you may not have read the comment in question - it wasn't that LLMs are a good toy, it was just that LLMs are good at a particular aspect of the authors writing.
